Specification forming part of Letters Patent Non. 2l 1,352, datedJanuary 14, V1879; application filed November 3o, 187s.

To all whom fit may concern.:

Beit known that I, GILLoUs B. SMITH, of Bath, in the county of Steubenand State of New York, have invented certain new and useful Improvementsin `Measuring-Funnels; and I do hereby declare that the following is afull, clear, and exact description thereof, which will enable othersskilled in the art to which it appertains to make and use thesame,reference being had to the accompanying drawings, and to letters ofreference marked thereon, which form a part of this specification and inwhich Figure '1 is a central vertical section of my improvedmeasuring-funnel, showing the mouth of the eduction-tube closed by thevalve. Fig. 2 is a similar view, showing the ,valve removed from themouth of the eduction-tube; and Fig. 3 is a top view of my improvedfunnel.

Gorrespondin g are denoted by similarletters of reference.

My invention appertains to certain improvements in measuring-tunnels;and it consists of a spring attached at one end to the handle of thefunnel, and following the curve of said handle; secondly, of a springattached at one end to the handle of the funnel, and following the curveot' said handle, having a slot, which receives the upper end of thevalve-stem; and, thirdly, of a concaved` collar, secured to the insideof the funnel near the mouth of the eduction tube, substantially ashereinafter more fully described and claimed.

The object of my invention is to provide the trade with a cheap andefficient measurin g-funnel, the valve of which can be easily andreadily controlled by the operator.

In the annexed drawings, A marks a suitable frame supported upon legs a,and provided with a graduated scale or bar, B, with or without lugs b.Firmly secured to the handle C, preferably to the under part, is aspring, D, which extends upwardly and follows the curve of said handle,its free end being provided with a slot, which receives the upper end ofthe valve-stein E.

Attached to the top of the valve-stem E is a thumb-piece, c, having abent portion, c',

parts in the several gures' which `catches under the spring-hook-F,secured to the funnel. The valve-stem E extends down into the funnel Aunder a confiningplate, Gr, and is hinged to the valve E', preferablymade of a rubber base, surmounted by a metal cap.

Secured to the inside ot' the funnel near its bottom, and on the sideopposite to the conlining-plate G, is a concave collar, H, which, whenthe valve is forced down over the eduction-tube I, holds thevalve uponits seat and completely closes the said eduction-tube. eduction-tub'e Iis fluted, as clearly shown in Fig. 1, to allow the escape of air fromthe jug or other receptacle as it is being iilled from the funnel.

When it is desired to close the mouth ofthe eduction-tube Iin order toiill or relill the funnel, press the valve-stem down by means of thethumb, `pressing on the thumb-piece c until the projection c is caughtand held by the spring-hook F, when the valve E will be pressed and heldtightly over the mout-l1 Aot the eduction-tube I by the concaved collarH and lsaid spring-hook F, as clearly shown in Fig. 1.

To allow the contents to escape `from the funnel, press with the thumbon the springhool; F, when the projection c will be released from saidspring-hook, and the spring D will draw the valve from over theeductiontube.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s-

1. In a measuring-funnel, the slotted spring D, secured to the outsideof the handle and extending inwardly, in combination with a valve-stemand a spring-hook, substantially as and for the purpose set forth. i

2. In a measuring-funnel, the slotted spring D, secured to the outsideof the handle and extendinginwardly, provided with a thumbpiece, e, andprojection e, in combination with `a valve-stein and a spring-hook,substantially as and for the purpose set forth.

. 3. In combination with a funnel, A, provided with the con caved collarH, plate G, and

spring-hook F, of the hinged valveE, valve- 1 The bent projection e',spring D, andl rIn testimony that I claim the foregoingas my own Ihereunto affix my signature 1n presence of two witnesses.
